框架是什么,为什么要用框架. 框架解决了什么.
我是刚学的. 把一简单的select 结果放到网页上.
直接写点php 代码就行了.
用框架干什么. 整个框架一大堆代码,读也读不懂.鬼知道里面发生了什么事.
而且要用框架,还要花很多时间学习它.
我"把一简单的select 结果放到网页上" 这件事上,我感觉框架屁用没有.
网上只说框架方便程序员,做了基础工作. 都是一些废话.
谁能举行个实例说下,框架到底起到了什么作用.

框架有点像类库
比如处理数据使用ORM类 自动处理URL 动态静态切换 权限系统
如果不是你还得做很多工作
queryphp 框架基本是类库

不要被“名词”吓到,也许同样的“名词”会变成你手中的“法宝”
什么是“框架”,框架是应用程序“模板”
就好比“八股”文章,不论好坏,按照规则填填就是
什么是“应用程序”,应用程序是完成某项特定任务的代码堆砌
也可以说是“套路”
当你完成了一、二个项目后,你是不会放弃承载着你大量心血的“代码集”的
你会在第三、第四...个项目中重复你的思路、代码,当然也包括改进或创新
于是,“框架”出现了......

框架,只是简化了程序员的工作。
将很多的类库集成到一起。
你会用框架就行,不需要理解框架是怎样做到这一点的。它是怎样做到的。 这些你可以不理。当然你想做一个出色的程序员,去理解是有必要的
------解决方案--------------------
对你现在的水平,框架是一个垃圾,或者以后也是
不信你直接输出 echo 'Hello you.'; 和在框架下输出字符 Hello you看有什么区别?
再分别循环十万次输出看那个效率?
对于以上两个问题你能说出结果,并测试过,就知道框架有什么用,什么时候用,能真的解决问题吗。
------解决方案--------------------
这句牛。。。
仅个人感受。
我是用ci 框架的。
用后和用前的差别。
1 我不再为一些基础类库去烦了。
2 我知道配置在哪,模版在哪,如何写helper 如何去libraries 如何hook,如果是以前,自己单独写这些时,经常因摆放位置不当到处找文件。
3 框架提供了很多很好的服务。
4 如果你觉得框架垃圾,请先在工资上超越用框架的人。个人觉得,楼主这心态,工资不会超过5000.
